Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

DETAILED DESCRIPTION

[0046] FIG. 1 is a schematic of a beverage dispensing system 10 including a beverage dispensing device 15 configured to combine water with a pre-packaged nutritional powder or liquid concentrate provided in a disposable container or pod 20 to produce a reconstituted formula. The beverage dispensing device 15 is then operable to dispense the reconstituted formula into a drinking vessel 25, such as a bottle, mug, or cup.

[0047] Referring also to FIGS. 2a-2d, the pod 20 includes a container body 30 and a flexible lid 35 that collectively define an enclosed storage volume ranging from

approximately 60 milliliters (ml) to approximately 170 ml in one or more chambers. The container body 30 includes a bottom wall 45 and a side wall 50 extending from and integrally formed as one piece with the bottom wall 45. The side wall 50 terminates in a generally flat rim or flange 55 at an open upper end of the container body 30. In some applications, at least a portion of the bottom wall 45 and/or side wall 50 may have a generally arcuate shape.

[0048] The pod 20 is sized to receive from approximately 2 grams to approximately 150 grams of the nutritional powder or liquid concentrate through the open upper end, after which the lid 35 is hermetically sealed to the flange 55. The powder has a bulk density of approximately 0.3 g/cc to approximately 0.8 g/cc with a particle size from approximately 10 microns to approximately 500 microns, occupying between approximately 60% and approximately 90% of the enclosed volume. The container body 30 is molded,

thermoformed, or otherwise constructed from a food-safe plastic material, such as polypropylene or polyethylene, and may include additional materials in a multi-layer structure. As one example, a gas barrier material such as ethylene vinyl alcohol (EVOH) may constitute a portion of the container body 30. The lid 35 can be made of a polymer film, metal foil, or any other material suitable for affixing to the flange 55.

[0049] At least one of the lid 35 and the container body 30 is configured to receive an injector or similar device (not shown) through which water, air, or other fluids may be introduced to assist in mixing and reconstitution of the nutritional powder or liquid concentrate within the enclosed volume. The introduced fluid(s) may be pre-filtered or alternatively pass through a filtration unit disposed within the pod 20. Additionally, the introduced fluid(s) may be pressurized to a pressure greater than atmospheric pressure.

[0050] The pod 20 further includes an outlet member 60 having a substantially elongated body with a first end coupled to the container body 30, a second or distal end opposite the first end, a longitudinal axis extending between the first and second ends, and a conduit extending through the outlet member. The conduit is in fluid communication with the enclosed volume via the first end and has an inner diameter greater than about 4 millimeters (mm) and preferably between approximately 4 mm and approximately 8 mm. The outlet member 60 may be integrally formed as a part of the container body 30 and is positioned for selectively dispensing from the pod 20, with the assistance of the introduced fluid(s), a nutritional product incorporating the nutritional powder or liquid concentrate. The dispensed product volume can range from approximately 50 ml to approximately 280 ml, and is preferably between approximately 70 ml and approximately 220 ml. The product may be dispensed through the outlet member 60 at a flow rate between about 1 milliliter per second (ml/s) and about 10 ml/s. The temperature of the dispensed nutritional product is product dependent and can range from approximately 5°C to approximately 50°C.

[0051] The outlet member 60 has a length, measured along the longitudinal axis from the first end to the second end, between approximately 5 mm and approximately 40 mm.

Accordingly, in some embodiments, the outlet member 60 can be greater than about 5 mm in length. In other embodiments, the outlet member 60 can be greater than about 10 mm in length. In other embodiments, the outlet member 60 can be greater than about 20 mm in length. The length of the outlet member 60 can be greater than half of a height of the pod 20, measured between the bottom wall 45 and the flange 55. In some embodiments, the length of the outlet member 60 can be greater than the height of the pod 20. In some embodiments, the inner diameter of the conduit is approximately half the length of the outlet member 60. In other embodiments, the inner diameter is approximately one fourth the length of the outlet member 60. In some embodiments, the inner diameter is greater than about one-sixth the maximum outer diameter of the container body 30. In other embodiments, the inner diameter is greater than about one-third of the outer diameter of the container body 30. In any and all configurations hereinafter described, the outlet member 60 is sized and positioned with respect to the beverage dispensing device 15 such that the entirety of the reconstituted formula may be dispensed free of contact with any portion of the beverage dispensing device 15.

[0052] As described in greater detail below, the outlet member 60 is adjustable between a first configuration in which the outlet member is in fluid communication with the enclosed volume and a second configuration in which the outlet member is not in fluid communication with the enclosed volume. Accordingly, the outlet member 60 may be adjusted to selectively control the flow of fluid through the outlet member 60. [0053] In general, the pod 20 includes a barrier, such as a seal or membrane, which inhibits ingress of air and any foreign matter into the enclosed volume prior to movement of the outlet member 60 to the open configuration. In other words, when the outlet member 60 is in the closed configuration, the pod is a closed system and its contents are isolated from the surrounding environment. When moved to the open configuration, the barrier is breached (e.g., due to rupture of a membrane, misalignment of a seal, etc.) to permit fluid flow through the outlet member 60 to dispense the nutritional product. Thus, when the outlet member 60 is in the open configuration, the pod 20 is an open system, and mass flow may occur between the pod 20 and the surrounding environment.

[0054] The container body 30 and the outlet member 60 may be formed separately (e.g., using an injection molding, thermoforming, 3-D printing, or other process) and subsequently assembled together using adhesive, mechanical fasteners, welding, to include induction welding, ultrasonic welding, conductive welding, or rotational welding, or any other suitable means. Alternatively, the container body 30 and the outlet member 60 can be integrally formed together as a single part. The outlet member 60 may take on a variety of different structures, features, or means of operation, and various embodiments of the outlet member 60 are described in greater detail below. In some embodiments, the outlet member 60 may be automatically actuated through engagement with one or more components of the dispensing device 15 (FIG. 1). Regardless of the method of actuation, the outlet member 60 is adjustable between the closed configuration and the open configuration such that the reconstituted formula does not come into direct contact with any part of the dispensing device 15.

[0055] In the embodiment of the pod 20 illustrated in FIGS. 2a-2d, the first end of the outlet member 60 is coupled to the container body 30 at the bottom wall 45. The first end may be coupled to the bottom wall 45 by a living hinge or other hinge arrangement, examples including but not limited to a butt hinge, a T-hinge, a strap hinge, a gate hinge, a soss hinge, a piano hinge, and a butterfly hinge, so that the outlet member 60 is pivotally movable relative to the container body 30. The living hinge includes a thin, bendable segment integrally formed with the bottom wall 45 and with the first end of the outlet member 60 to connect the outlet member 60 with the container body 30. The outlet member 60 is pivotable about the first end between the closed configuration (FIGS. 2a and 2c) and an open configuration (FIGS. 2b and 2d). In the closed configuration, the outlet member 60 extends generally parallel to the bottom wall 45 and is received within a recess formed in the bottom wall 45 so that the pod 20 has a relatively compact shape. When pivoted to the open configuration, the outlet member 60 extends in a normal direction from the bottom wall 45. Accordingly, the pod 20 may be oriented vertically to dispense the nutritional product through the outlet member 60.

[0056] Alternatively, the outlet member 60 may be configured to dispense the reconstituted formula when positioned from the bottom wall 45 at an angle less than 90 degrees from the closed configuration. The operable angle may range, for example, from approximately 30 degrees to approximately 90 degrees. In such embodiments, the nutritional product dispensed through the outlet member 60 is directed to impinge on a sidewall of the drinking vessel 25, resulting in reduced foaming and additional mixing within the drinking vessel 25. The outlet member 60 can also have a variety of different cross-sectional shapes (e.g., elliptical, elongated, rectangular, non-uniform, varying, etc.) and can extend from the bottom wall 45 at any location with respect to the container body 30. In some embodiments, the outlet member 60 can include one or more bends or turns along its length. For example, the outlet member 60 may initially extend from the container body as shown in FIGS. 2a-2d and thereafter include a bend or curve that alters the trajectory of the dispensed product.

[0057] Referring to FIGS. 3a-3d, a pod 120 according to another embodiment includes an outlet member 60 having its first end coupled to the container body 30 at the side wall 50. In the closed configuration, the outlet member 60 extends generally parallel to the side wall 50 and is received within a recess formed in the side wall 50 so that the pod 120 again has a relatively compact size. When pivoted to the open configuration, the outlet member 60 extends in a generally normal direction from the side wall 50. Accordingly, the pod 120 may be oriented on its side within the beverage dispensing device to dispense the nutritional product through the outlet member 60. Alternatively, the outlet member 60 can extend from the side wall 50 at an angle, as described above for FIGS. 2a-2d, so that the pod 120 may be positioned in other orientations to dispense the nutritional product.

[0058] In yet another embodiment (not shown), the outlet member 60 can be positioned to extend beyond the lid 35 when in the open configuration so that the pod may be oriented upside down to dispense the nutritional product.

[0059] Referring to FIGS. 5a-5b, in the illustrated embodiments, a puncturable membrane or seal 70 is positioned proximate the first end of the outlet member 60 to fluidly isolate the outlet member 60 from the storage volume when the outlet member 60 is in the closed configuration (FIG. 5 a). The first end includes an engagement portion 75, such as a sharp edge or pointed tip, which comes into contact with the seal 70 and ruptures the seal 70 when the outlet member 60 is pivoted to the open position (FIG. 5b). This permits fluid

communication between the enclosed volume and the conduit. A flexible shroud 80 surrounds the interface between the first end and the container body 30 to prevent fluid from leaking around the outlet member 60 and to inhibit foreign material from entering the first end of the outet member 60 when in the closed position.

[0060] With reference to FIGS. 4a-4d, a pod 220 according to another embodiment includes an outlet member 60a having its first end coupled to the container body 30 at the bottom wall 50, similar to the pod 20 described above with reference to FIGS. 2a-2d. Unlike the pod 20, however, in the closed configuration, the outlet member 60a of the pod 220 extends generally parallel to the bottom wall 45 along the exterior of the bottom wall 45. When pivoted to the open configuration, the outlet member 60a extends in a generally normal direction from the bottom wall 45, so that the pod 220 may be oriented vertically to dispense the nutritional product through the outlet member 60a.

[0061] Referring to FIGS. 6a and 6b, in the illustrated embodiment, the first end of the outlet member 60a includes an engagement portion 75a, which may be an arcuate projection extending from the first end, that comes into contact with the seal 70 and ruptures the seal 70 when the outlet member 60a is pivoted to the open position (FIGS. 4b and 4d). This permits fluid communication between the enclosed volume and the conduit. The exterior of the outlet member 60a creates a seal with the portion of the pod surrounding the membrane (e.g., via an interference fit, one or more sealing elements (not shown), etc.) to prevent fluid from leaking at the interface between the outlet member 60a and the container body 30.

[0062] In the previously-described embodiments, the seal 70 may be ruptured when the outlet member 60, 60a is pivoted by at least 10 degrees about the first end. Alternatively, the seal 70 may be ruptured when the outlet member 60, 60a is pivoted by at least 90 degrees about the first end. The seal 70 can be made of any suitable polymer film, such as a thinner version of the pod side wall 50 or bottom wall 45, metal foil, or any material able to selectively fail in response to contact with the engaging portion 75, 75a of the outlet member 60, 60a. Alternatively, the seal 70 can be ruptured in response to translational movement of the outlet member 60 with respect to the container body 30. In such embodiments, the outlet member 60 is slidably connected to the container body 30 so that the engagement portion 75 on the first end can be moved into and through the seal 70 to rupture the seal 70. In yet other embodiments, the seal 70 can be ruptured by compressing at least a portion of the outlet member 60 proximate the seal 70.

[0063] Referring to FIGS. 7a and 7b, an outlet member 60b according to one embodiment may include a first portion 77b extending from the container body 30 and a second portion 79b slidably coupled to the first portion. In a closed configuration of the outlet member 60b, a plug 81b affixed to the first portion 77b is received in a corresponding orifice 83b in the second portion 79b to substantially seal the outlet member 60b. The second portion 79b may be moved relative to the first portion 77b along the longitudinal axis of the outlet member 60b to define an open configuration (FIG. 7b) in which the plug 81b is spaced from the orifice 83b. As such, fluid may flow around the plug 81b and through the orifice 83b to be dispensed from the outlet member 60b.

[0064] In the following embodiments, illustrated in FIGS. 8a- 13b, the seal can be selectively opened or ruptured by rotating all or a portion of the outlet member relative to the container body 30 about the longitudinal axis of the outlet member. For example, the outlet member may be opened for fluid flow when a movable portion of the outlet member is rotated relative to the remainder of the outlet member by at least 10 degrees about the longitudinal axis, when the movable portion is rotated at least 90 degrees about the longitudinal axis, or when the movable portion is rotated at leastl 80 degrees about the longitudinal axis.

[0065] With reference to FIGS. 8a and 8b, in one embodiment, an outlet member 60c has a first portion 77c including the first end affixed to the container body 30 and a second portion 79c including the second end rotatably coupled to the first portion 77c. In the illustrated embodiment, the second portion 79c is threadably engaged with the first portion 77c such that rotation of the second portion 79c relative to the first portion 77c causes linear displacement of the second portion 79c relative to the first portion 77c along the longitudinal axis. The second portion 79c includes a seal plate 70c that abuts an open distal end of the first portion 77c to define the closed configuration of the outlet member 60c (FIG. 8a). In this configuration, the seal plate 70c prevents fluid from being dispensed through the outlet member 60c. When the second portion 79c is rotated, the second portion 79c is displaced along the longitudinal axis, moving the seal plate 70c away from the distal end of the first portion 77c to define the open configuration of the outlet member 60c (FIG. 8b).

[0066] Referring to FIGS. 9a and 9b, in one embodiment, an outlet member 60d has a first portion 77d including the first end affixed to the container body (not shown) and a second portion 79d including the second end rotatably coupled to the first portion 77d. The first portion 77d includes a plurality of circumferentially-spaced apertures 85d and the second portion 79d include a corresponding plurality of circumferentially-spaced covers 87d that may be aligned with the apertures 85d to substantially seal the apertures 85d when the outlet member 60d is in the closed configuration (FIG. 9a). When the second portion 79d is rotated relative to the first portion 77d, the covers 87d become misaligned with the apertures 85d to permit fluid flow therethrough (FIG. 9b).

[0067] Referring to FIGS. 10a and 10b, in one embodiment, an outlet member 60e has a first portion 77e extending from the container body 30 and a second portion 79e threadably coupled to the first portion 77e. In a closed configuration of the outlet member 60e, a plug 81e affixed to the first portion 77e is received in a corresponding orifice 83 e in the second portion 79e to substantially seal the outlet member 60e. The second portion 79e may be moved relative to the first portion 77e along the longitudinal axis of the outlet member 60e by rotating the second portion 79e about the first portion 77e. In an open configuration (FIG. 7b), the plug 81e is spaced from the orifice 83 e. As such, fluid may flow around the plug 81e and through the orifice 83e to be dispensed from the outlet member 60e.

[0068] Referring to FIGS. 1 1a and 1 lb, in one embodiment, an outlet member 60f has a first portion 77f extending from the container body 30 and a second portion 79f threadably coupled to the first portion 77f. A seal or membrane 70f extends across a distal end of the first portion 77f to define a closed configuration of the outlet member 60f. The second portion 79f includes an engaging portion 75f (e.g., a pointed tip) that may be moved into the seal 70f by rotating the second portion 79f about the first portion 77e. The engaging portion 75f punctures the seal 70f to allow fluid flow therethrough and to define an open

configuration of the outlet member 60f.

[0069] Referring to FIGS. 12a and 12b, in another embodiment, an outlet member 60g has a first portion 77g extending from the container body 30 and a second portion 79g threadably coupled to the first portion 77g. A seal or membrane 70g extends across a distal end of the first portion 77g to define a closed configuration of the outlet member 60g. The second portion 79g includes an engaging portion 75g in the form of a circumferential projection that may be moved into the seal 70g by rotating the second portion 79g about the first portion 77g. The engaging portion 75g is configured to peel at least a portion of the seal 70g away from the distal end of the first portion 77g to allow fluid flow through the distal end and to define an open configuration of the outlet member 60g. In yet another embodiment (not shown), the seal 70g includes an external projection, such as a knob, integrally formed with the seal or otherwise adhered thereto, and the second portion 79g is configured to grasp or engage the projection in the closed configuration such that the integrity of the seal is compromised upon rotation of the second portion 79g into the open configuration.

[0070] Referring to FIGS. 13a and 13b, in another embodiment, an outlet member 60h has a first portion 77h extending from the container body 30 and a second portion 79h threadably coupled to the first portion 77h. A sealing door 70h biased to extend across the interior of the outlet member 60h is pivotally coupled at one side to the outlet member 60g. The sealing door 70h includes an engaging portion 75h extending through the exterior of the outlet member 60h. The second portion 79h is rotatable about the first portion 77h to move the second portion 79h into engagement with the engaging portion 75h, causing the sealing door 70h to pivot to an open configuration (FIG. 13b) in which fluid is allowed to flow through the outlet member 60h. In yet another embodiment (not shown), the sealing door 70h is in the form of a projection that ruptures a seal extending across a distal end of the first portion 77h upon rotation of the second portion 79h.

[0071] For any of the above embodiments, the outlet member may be actuated between the closed and open configurations through direct user-manipulation or by an actuating portion (not shown) of the dispensing device 15. The actuating portion can include one or more levers, hooks, clamps, or other mechanical means for moving the outlet member from the closed configuration to the open configuration. The actuating portion may be configured to move the outlet member automatically in response to an actuating signal generated by a controller (not shown) of the beverage dispensing device. The actuating signal may be generated a predetermined time period after the dispensing unit begins the reconstitution process. In some embodiments, the predetermined time period is between approximately 2 seconds and approximately 60 seconds. Alternatively, the actuating signal may be generated in response to a sensed condition. For example, the dispensing device 15 may include one or more optical sensors able to measure the relative proportion of nutritional powder or liquid concentrate to reconstituted fluid. The actuating signal may be generated when it is sensed that at least approximately 75 percent of the nutritional powder or liquid has been reconstituted. The container body 30 may include one or more substantially transparent portions to improve performance of the one or more optical sensors.

[0072] FIGS. 14a- 19 illustrate various additional features that may be incorporated, alone or in combination, into any of the pods described herein.

[0073] With reference to FIGS. 14a and 14b, any of the pods described herein may further include a screen 101 (FIG. 14a) or a soluble membrane 103 (FIG. 14b) at the first end of the outlet member 60 to inhibit nutritional powder from entering the outlet member 60 before being reconstituted. The screen 101 may include a metal or polymer mesh, a paper, fabric, or fiber filter, or any other means for substantially inhibiting particles ranging from approximately 10 microns to approximately 500 microns or larger from passing through into the outlet member 60. The soluble membrane 103 at least partially dissolves once exposed to the water or other fluid introduced into the pod during operation of the fluid dispensing device 15. In some embodiments, the soluble membrane 103 may be replaced by a pressure and/or temperature sensitive burst disk.

[0074] Referring to FIGS. 15a and 15b, any of the pods described herein may include an end seal 105 at the second end of the outlet member 60. The end seal 105 inhibits foreign matter from entering the outlet member 60 through the second end to maintain a sanitary environment within the outlet member 60. In one embodiment, the end seal 105 is a metal foil or polymer film adhered to the second end. Before use, the seal 105 is removed (e.g., peeled off) by a user (FIG. 15b). Alternatively, the seal 105 may be configured to rupture when exposed to a predetermined pressure or temperature, or the seal 105 may be a soluble membrane that at least partially dissolves once exposed to the water or other fluid introduced into the pod, or the reconstituted contents within the pod, during operation. In other embodiments, the end seal 105 can be a plug or solid tip that is cut off by the user or by a cutting apparatus included on the dispensing device 15 before the pod is used, or otherwise removed by engagement with a portion of the dispensing device 15 during operation. The plug or solid tip can be integrally formed with the second end of the outlet member 60 or can be otherwise affixed to the second end. For example, the second end may be dipped in wax to provide a solid tip or plug on the second end. [0075] Referring to FIGS. 16-19, any of the pods described herein may include one or more mixing or flow affecting features located within the outlet member 60. These features may facilitate mixing of the nutritional powder or concentrate liquid with the fluid injected into the pod, minimize foaming that may occur when the nutritional product is dispensed into the drinking vessel 25 (FIG. 1), inhibit gurgling within the outlet member 60, or further streamline the flow of fluid as it is dispensed from the outlet member 60.

[0076] Referring to FIG. 16, in one embodiment, the outlet member 60 includes a flow- affecting portion 107 having a plurality of internal, helical depressions 109. Helical ridges 11 1 are formed between adjacent depressions. The depressions 109 and ridges 11 1 create rifling within the outlet member 60 and influence the fluid flow through the outlet member 60 to induce a swirling or vortex effect within the fluid. The flow-affecting portion 107 of FIG. 16 may reduce turbulence in the fluid before it is dispensed through the second end of the outlet member 60. This in turn may reduce overspray or undesirable foaming.

[0077] Referring to FIG. 17, in another embodiment, baffles 113 are integrally formed along an inner circumferential surface of the outlet member 60 and are positioned within the outlet member 60 to agitate fluid flowing through the outlet member 60. Each of the baffles 113 includes an upstream surface and a downstream surface as referenced with respect to the direction of fluid flow through the outlet member 60. The baffles 113 may be positioned proximate the first end of the outlet member 60, proximate the second end, or at any other location within the outlet member 60. In the illustrated embodiment, each of the baffles 113 is substantially planar and is oriented perpendicular to the longitudinal axis of the outlet member 60. Alternatively, one or more of the baffles 113 may have an arcuate shape. In some embodiments, the upstream surface of one or more of the baffles 1 13 may be angled between approximately 30 degrees and approximately 45 degrees with respect to the longitudinal axis. In other embodiments, the upstream surface of one or more of the baffles 113 may be angled between approximately 10 degrees and approximately 35 degrees with respect to the axis. The illustrated baffles 1 13 are staggered such that each baffle at least partially overlaps in the axial direction (i.e. along the longitudinal axis). Alternatively, the baffles 1 13 may be positioned so that the baffles do not overlap in the axial direction.

[0078] Referring to FIGS. 18 and 19, in another embodiment, the cross-sectional area of the outlet member 60 may vary along the length of the output member. The cross-sectional area may vary due to a varying wall thickness along the outlet member 60 or due to a varying diameter of the outlet member 60. Additionally or alternatively, the cross-sectional shape of the outlet member 60 may vary along the length of the output member. In the embodiment illustrated in FIG. 18, the outlet member 60 converges and diverges to create a venturi or half-venturi effect that promotes mixing. In the embodiment illustrated in FIG. 19, the outlet member 60 is generally frustoconical or tapered and converges at a constant rate.

[0079] FIG. 20 illustrates a pod 320 according to another embodiment. A plurality of engagement members 1 15 in the form of fins or keys extends along the side wall 50 between the flange 55 and the bottom wall 45. The engagement members 1 15 cooperate with corresponding keyways located in a pod receptacle (not shown) of the beverage dispensing device 15 to releasably couple the pod 320 and the beverage dispensing device 15, and/or to orient and/or stabilize the pod 320 within the beverage dispensing device 15. The engagement members 115 can be integrally formed with the side wall 50 or the bottom wall 45 or can be affixed to either via any suitable means, such as welding, to include induction welding, ultrasonic welding, conduction welding, or rotational welding. Although illustrated as fins, the engagement members 115 can be of various shapes, e.g., knobs, blocks, ridges, or any form of projection. In some applications, only one engagement member 115' is associated with the container body 30 (FIG. 21). In the embodiment of a pod 420 illustrated in FIG. 21, the engagement member 1 15' is a rounded lobe that cooperates with a corresponding keyway (not shown) in the pod receptacle.

[0080] With reference to FIG. 22, in one embodiment, a pod 520 includes a plurality of circumferentially-spaced engagement members 1 17 that extends axially along the exterior of the outlet member 60. The engagement members 1 17 provide spacing between the outlet member 60 and the beverage dispensing device 15 to reduce the reduce the likelihood of the dispensed nutritional product coming into contact with any portion of the beverage dispensing device 15. Furthermore, the engagement members 117 may serve to orient and/or stabilize the pod 520 within the beverage dispensing device 15. The engagement members 117 can be integrally formed with the outlet member 60 or can be affixed to the outlet member 60 via any suitable means, such as welding as previously described. Although illustrated as fins, the engagement members 117 can be of various shapes, e.g., knobs, blocks, ridges, or any form of projection.

[0081] In some embodiments, any of the pods described herein can further include an actuation member (not shown), at least partially positioned within the outlet member between the first end and the second end. The actuation member may be operable independently of the rotation or pivoting of the outlet member to provide additional control of the fluid flow through the outlet member. The actuation member may take a variety of different structures, features, or means of operation, and various embodiments of the actuation member are described in greater detail below. In some embodiments, the actuation member may be actuated when a pressure difference between the upstream side and the downstream side exceeds a predetermined pressure. In other embodiments, the actuation member may be automatically opened in response to other environmental conditions, such as elevated temperature or exposure to liquid. In yet other embodiments, the actuation member may be automatically opened through engagement with one or more components of the dispensing device. In some embodiments, the actuation member can be a mechanically-actuated valve, examples including but not limited to a butterfly valve, globe valve, gate valve, or ball valve, that receives a rotational or other mechanical input from an actuating portion of the dispensing device to actuate the valve. The actuating portion can include, for example, a linearly-displaceable rack that meshes with a pinion coupled to the valve. To actuate the valve, the rack is displaced, causing the pinion to rotate along the rack and thereby providing a rotational input to the valve. The actuating portion can additionally or alternatively include one or more servos, solenoids, or other actuators coupled to the valve by one or more gears, linkages, or any other suitable arrangements. In some alternative embodiments, the actuation member includes a pressure-actuated valve, such as a check ball valve, a reed valve, a duckbill valve, a foil burst disk, or any other suitable type of one-way valve or check valve.
